Abstract
A forced lubrication structure of a single-cylinder diesel engine comprises a body oil suction duct, a tooth cover oil suction duct, an oil pump, a tooth cover oil outlet duct and a body oil outlet duct, wherein the oil pump is arranged on the inner side of a gear chamber cover, the tooth cover oil suction duct is communicated with the body oil suction duct, the tooth cover oil outlet duct is communicated with the body oil outlet duct, the tooth cover oil suction duct and the tooth cover oil outlet duct are both communicated with the oil pump, the oil pump is driven by a cam shaft, and an oil filter cover is arranged at the suction port end of the body oil suction duct. The engine oil filter cover consists of a filter frame and filter cloth, wherein the filter cloth is fixed on the filter frame, and the periphery of the filter cloth is provided with a rim. Because the suction port end of the oil suction passage of the engine body is provided with the engine oil filter cover, impurities contained in the engine oil in the engine body can be effectively filtered by the filter cloth, the engine oil sucked by the engine oil pump is ensured to be clean, and the phenomenon that the oil pump is blocked or the crankshaft bites the bush due to the unclean engine oil is fundamentally avoided.
Description
Technical field:
The utility model relates to a kind of single cylinder diesel of pressure lubrication, relates in particular to the forced lubrication structure of single cylinder diesel.
Background technique:
In the single cylinder diesel of pressure lubrication, lubricating between crank-shaft link neck and the connecting rod bearing shell mainly comes fuel feeding by oil pump, single cylinder diesel for little cylinder diameter, reason owing to compact structure, in the pressure lubrication oil circuit, all lack oil filter, the inlet port of oil pump directly feeds the bottom of body, prolongation along with the diesel engine activity duration, the quality of body inner engine oil can constantly descend, impurity content in the oil can be on the increase, diesel engine is when work in addition, and the machine oil in the body constantly vibrates, and the impurity in the machine oil can swim in the fluid, in case containing the machine oil of impurity is inhaled in the pressure lubrication oil circuit, just may cause the stuck or bent axle of oil pump to be stung watt, make the diesel engine can't proper functioning, this be one of major failure of small-sized single cylinder pressure lubrication diesel engine.
Summary of the invention:
In order effectively to overcome existing single cylinder diesel above shortcomings, improve the functional reliability of diesel engine, the purpose of this utility model has provided a kind of forced lubrication structure of single cylinder diesel, adopts such lubricating structure, can prevent effectively that the stuck or bent axle of oil pump stings watt.
The forced lubrication structure of single cylinder diesel described in the utility model, comprise body oil suction road, tooth lid oil suction road, oil pump, tooth lid oil road, body oil road, oil pump is installed in the inboard of gear chamber cover, tooth lid oil suction road communicates with body oil suction road, tooth lid oil road communicates with the body oil road, tooth lid oil suction road and tooth lid oil road all communicate with oil pump, and oil pump be is characterized in that by camshaft actuated: the aspiration port in body oil suction road is provided with the machine oil filter bowl.
Described machine oil filter bowl is made up of filter stand and filter cloth, offers several oil-feed apertures on filter stand equably, is fixed on the body by fastening piece, and filter cloth is fixed on the filter stand, and have all around be close to the body inwall along the limit.
Because the aspiration port in body oil suction road is provided with the machine oil filter bowl, the impurity that floats in the machine oil can effectively be filtered by filter cloth, thereby guarantee the machine oil of machine oil that oil pump sucked for cleaning, fundamentally stop the defective that totally do not cause the stuck or bent axle of oil pump to sting watt because of machine oil, improved the operational reliability of diesel engine.

Embodiment:
Be example with R168 type single-cylinder water cooled diesel engine below, and accompanying drawings embodiment of the present utility model:
The forced lubrication structure of R168 type single cylinder diesel, shown in accompanying drawing 1～4, comprise body oil suction road 1, tooth lid oil suction road 2, oil pump 3, tooth lid oil road 4, body oil road 5, oil pump 3 is installed in the inboard of gear chamber cover 9, tooth lid oil suction road 2 communicates with body oil suction road 1, tooth lid oil road 4 upper ends communicate with machine oil indicator mounting hole 14, the right side communicates with body oil road 5, tooth lid oil suction road 2 and tooth lid oil road 4 all communicate with oil pump 3, oil pump 3 is driven by camshaft 8 parts, aspiration port in body oil suction road 1 is provided with machine oil filter bowl 6, described machine oil filter bowl 6 is by filter stand 61, filter cloth 62 is formed, and offers several oil-feed apertures 63 on filter stand 61 equably, is fixed on the body 7 by fastening piece 64, filter cloth 62 is fixed on the filter stand 61, and have all around be close to the body inwall along the limit.
The path of the lubricating oil path of machine oil is: the machine oil in the body 7 filters through filter cloth 62 and enters body oil suction road 1 by the oil-feed aperture 63 on the filter stand 61, turn to and enter tooth lid oil suction road 2 stream inhalation machine oil pumps 3, the lubricant oil that has pressure is from tooth lid oil road 4, body oil road 5, fuel-displaced aperture 10, along crankshaft main bearing 12, oil thrower ring 11 is transported to crank-shaft link neck oilhole 13 places, thereby lubricated bent axle and bearing shell, the impurity that is contained in body 7 inner engine oils can effectively be filtered by filter cloth 62, thereby guarantee machine oil that oil pump 3 sucked machine oil, fundamentally stopped not sting the generation of watt accident because of machine oil does not totally cause the stuck or bent axle of oil pump 3 for cleaning.
